TNG: "The Chase" (s6e20)

THE BRITISH MUSEUM is alive and well in the 24th century in the form of Captain Picard's old archeology professor Galen, whose shuttlecraft no doubt holds artifacts from countless civilizations taken from their native lands with a reckless abandon. But during all that grave robbing, Galen stumbled upon proof that there is no God, at least as we understand one. His death spurs Picard to take the Enterprise on a rogue mission to complete a galactic jigsaw puzzle. 

Bryan & Kristen review a pivotal episode for Picard's backstory that just so happens to be the impetus for the season mystery in Star Trek: Discovery's final season. They also talk about the beauty of Grace Kelly and escape rooms. Is this one a TREK, MARRY, or KILL?
